Delfi Medical Innovations Inc. (‘Delfi’) warrants the P.T.S. Portable Tourniquet System (‘product’) for one year from date of purchase. During the warranty period, Delfi will repair or replace, at its option, any product which is defective in materials or workmanship or which fails to meet the published specification for that model.
INTENDED USE The Delfi Portable Tourniquet System (P.T.S.) is intended to be used by qualified medical professionals to temporarily occlude blood flow in a patient's extremity during surgical procedures on that extremity. Tourniquets are generally used for operations lasting less than 90 minutes. Tourniquets have been found...
• Prolonged tourniquet time can also produce changes in the coagulability of the blood with increased clotting time. Always minimize tourniquet time. • Tourniquet paralysis may result from excessive pressure. Insufficient pressure may result in passive congestion of the limb with possible irreversible functional loss. Always use the minimum effective tourniquet pressure, as described in the medical literature.
We recommend that this inspection be performed by a qualified biomedical engineer or other person thoroughly familiar with electronic medical devices. If the unit is damaged, notify the carrier and Delfi immediately. If the initial inspection results are satisfactory, a functional and calibration check should be performed after an 8-hour charge.
CONTROLS, INDICATORS, DISPLAYS, AND CONNECTORS Refer to Figure 2.1 for the locations of the unit's controls, indicators, displays and connectors described below: ‘ON/STANDBY’ Button Turns the unit on or sets the unit to standby. In standby mode (powered off), the power to all instrument functions (i.e.

An AC power supply adapter is supplied with every P.T.S. unit. It is a sealed unit designed specifically for the P.T.S. Contact Delfi if your power supply needs service or replacement. Plug the locking connector on the AC power supply cord into the AC power receptacle on the P.T.S. unit (see above), and plug the AC power cord into a power outlet (see below) whenever using the unit where AC power is easily accessible.
AC power supply may fail and may pose an electrical shock hazard. WARNING: Use battery packs supplied by Delfi only. Do not use any other batteries. Use of an improper battery pack may cause irregular operation that could be hazardous to the patient and/or user, and may permanently damage the P.T.S.
c) Release the ‘PRESSURE + ‘ button. Within 2 seconds, the pressure display returns to “0”. d) Momentarily press the ‘PRESSURE – ‘ button and release (within 1 second). The pressure display reads "475*" (the new pressure set point) for 2 seconds. The pressure display then returns to “0”. e) Press and hold the ‘PRESSURE –...
2.5.6 “PRESSURE LOW” and “CUFF LEAK” ALARM CHECK: Connect the hose assembly and a cuff to the P.T.S. and press the ‘INFLATE’ button. The cuff inflates to the default pressure set point of 250 mmHg. Create a leak by partially detaching the hose from the unit while the cuff is inflated.

memory during power up and are active until the user adjusts them (see Sections 2.5.3 and 2.5.4). These default values can be modified by the user (see Section 2.6). WARNING: In all cases it is essential to check the pressure and time limit set points and confirm that they are the desired values before inflating the cuff.
ALARM CONDITIONS There are a number of conditions for which the P.T.S. will produce visual and audible alarms. Those conditions, indications and appropriate actions are shown in Table 2.1. The appropriate actions indicated are based on the most probable causes and should only be used as a guide. Other causes of alarm conditions may indicate a need for other actions.

2.8.1 ALARM SILENCE FUNCTIONS Most audible alarm tones may be silenced for 30 seconds by momentarily depressing the ‘PRESSURE + ‘, ‘PRESSURE – ‘, ‘TIME + ‘, or ‘TIME – ‘ button. At the end of the silenced period, the alarm tone will restart if the alarm condition has not been corrected.
